Ammine

★Ammine/Aromatic amine/aniline

★ —NH2

PREPARATION

1. From Nitrobenzene: (basically reduction)

Nitrobenzene + 6[H] → 1° Amine + 2H2O

Catalyst: Sn+ H2O or Cu, 270°C, 20 atm

2. By Hoffman Degradation reaction: (like decarboxilation)

Amide (—CONH2) + Br2 + KOH → 1° Amine + KBr + K2CO3 + H2O

CH3-CO-NH2 + Br + KOH → CH3-NH2 + KBr + K2CO3 + H2O

3. 2° & 3° Amine Production:

   1° Amine + CH3I → 2° Amine + HI

   2° Amine + CH3I → 3° Amine + HI

HNO2 IS VERY UNSTABLE

★HNO2 → Nitous Acid

★Reacts with itself

★both oxidation and reduction takes place (disproportion reaction)

★its not possible to keep alone

★made by mixing NaNO3 and HCl

★HNO2 breakdown: OH-NO
